BACKGROUND

The Fibroblast Growth Factor Receptors (FGFR) are receptor tyrosine kinases that bind to fibroblast growth factor (FGF) ligands. There are four FGFR proteins (FGFR1-4) that are capable of binding ligands and are involved in the regulation of many physiological processes including tissue development, angiogenesis, wound healing, and metabolic regulation. Upon ligand binding, the receptors undergo dimerization and phosphorylation leading to stimulation of the protein kinase activity and recruitment of many intracellular docking proteins. These interactions facilitate the activation of an array of intracellular signaling pathways including Ras-MAPK, AKT-PI3K, and phospholipase C that are important for cellular growth, proliferation and survival (Reviewed in Eswarakumar et al. Cytokine & Growth Factor Reviews, 2005, 16, 139-149). Aberrant activation of this pathway either through overexpression of FGF ligands or FGFR or activating mutations in the FGFRs can lead to tumor development, progression, and resistance to conventional cancer therapies. In human cancer, genetic alterations including gene amplification, chromosomal translocations and somatic mutations that lead to ligand-independent receptor activation have been described (Reviewed in Knights and Cook, Pharmacology & Therapeutics, 2010, 725, 105-117; Turner and Grose, Nature Reviews Cancer, 2010, 10, 116-129). Large scale DNA sequencing of thousands of tumor samples has revealed that FGFR genes are altered in many cancers (Helsten et al. Clin Cancer Res. 2016, 22, 259-267). Some of these activating mutations are identical to germline mutations that lead to skeletal dysplasia syndromes (Gallo et al. Cytokine & Growth Factor Reviews 2015, 26, 425-449). Mechanisms that lead to aberrant ligand-dependent signaling in human disease include overexpression of FGFs and changes in FGFR splicing that lead to receptors with more promiscuous ligand binding abilities. Therefore, development of inhibitors targeting FGFR may be useful in the clinical treatment of diseases that have elevated FGF or FGFR activity.

The cancer types in which FGF/FGFRs are implicated include, but are not limited to: carcinomas (e.g., bladder, breast, colorectal, endometrial, gastric, head and neck, kidney, lung, ovarian, prostate); hematopoietic malignancies (e.g., multiple myeloma, acute myelogenous leukemia, and myeloproliferative neoplasms); and other neoplasms (e.g., glioblastoma and sarcomas). In addition to a role in oncogenic neoplasms, FGFR activation has also been implicated in skeletal and chondrocyte disorders including, but not limited to, achrondroplasia and craniosynostosis syndromes.

There is a continuing need for the development of new drugs for the treatment of cancer, and the FGFR inhibitors described herein help address this need.

or a pharmaceutically acceptable of any of the aforementioned.

It is further appreciated that certain features of the disclosure, which are, for clarity, described in the context of separate embodiments, can also be provided in combination in a single embodiment. Conversely, various features of the disclosure which are, for brevity, described in the context of a single embodiment, can also be provided separately or in any suitable sub combination.

At various places in the present specification, substituents of compounds of the disclosure are disclosed in groups or in ranges. It is specifically intended that the disclosure include each and every individual subcombination of the members of such groups and ranges. For example, the term “C₁₋₆ alkyl” is specifically intended to individually disclose methyl, ethyl, C₃ alkyl, C₄ alkyl, C₅ alkyl, and C₆ alkyl.

At various places in the present specification various aryl, heteroaryl, cycloalkyl, and heterocycloalkyl rings are described. Unless otherwise specified, these rings can be attached to the rest of the molecule at any ring member as permitted by valency. For example, the term “a pyridine ring” or “pyridinyl” may refer to a pyridin-2-yl, pyridin-3-yl, or pyridin-4-yl ring.

The term “n-membered” where n is an integer typically describes the number of ring-forming atoms in a moiety where the number of ring-forming atoms is n. For example, piperidinyl is an example of a 6-membered heterocycloalkyl ring, pyrazolyl is an example of a 5-membered heteroaryl ring, pyridyl is an example of a 6-membered heteroaryl ring, and 1,2,3,4-tetrahydro-naphthalene is an example of a 10-membered cycloalkyl group.

For compounds of the disclosure in which a variable appears more than once, each variable can be a different moiety independently selected from the group defining the variable. For example, where a structure is described having two R groups that are simultaneously present on the same compound, the two R groups can represent different moieties independently selected from the group defined for R.

As used herein, the phrase “optionally substituted” means unsubstituted or substituted.

The term “substituted” means that an atom or group of atoms formally replaces hydrogen as a “substituent” attached to another group.

The substituents are independently selected, and substitution may be at any chemically accessible position. It is to be understood that substitution at a given atom is limited by valency. It is to be understood that substitution at a given atom results in a chemically stable molecule. A single divalent substituent, e.g., oxo, can replace two hydrogen atoms.

As used herein, the term “C_(i-j),” where i and j are integers, employed in combination with a chemical group, designates a range of the number of carbon atoms in the chemical group with i-j defining the range.

The compounds described herein can be asymmetric (e.g., having one or more stereocenters). All stereoisomers, such as enantiomers and diastereomers, are intended unless otherwise indicated. Compounds of the present disclosure that contain asymmetrically substituted carbon atoms can be isolated in optically active or racemic forms. Methods on how to prepare optically active forms from optically inactive starting materials are known in the art, such as by resolution of racemic mixtures or by stereoselective synthesis. Many geometric isomers of olefins, C≡N double bonds, and the like can also be present in the compounds described herein, and all such stable isomers are contemplated in the present disclosure. Cis and trans geometric isomers of the compounds of the present disclosure are described and may be isolated as a mixture of isomers or as separated isomeric forms.

Resolution of racemic mixtures of compounds can be carried out by methods known in the art. An example method includes fractional recrystallizaion using a chiral resolving acid which is an optically active, salt-forming organic acid. Suitable resolving agents for fractional recrystallization methods are, for example, optically active acids, such as the D and L forms of tartaric acid, diacetyltartaric acid, dibenzoyltartaric acid, mandelic acid, malic acid, lactic acid or the various optically active camphorsulfonic acids.

In some embodiments, the compounds of the disclosure have the (R)-configuration. In other embodiments, the compounds have the (S)-configuration. In compounds with more than one chiral centers, each of the chiral centers in the compound may be independently (R) or (S), unless otherwise indicated.

Compounds of the disclosure also include tautomeric forms. Tautomeric forms result from the swapping of a single bond with an adjacent double bond together with the concomitant migration of a proton. Tautomeric forms include prototropic tautomers which are isomeric protonation states having the same empirical formula and total charge. Example prototropic tautomers include ketone-enol pairs, amide-imidic acid pairs, lactam-lactim pairs, enamine-imine pairs, and annular forms where a proton can occupy two or more positions of a heterocyclic system, for example, 1H- and 3H-imidazole, 1H-, 2H- and 4H-1,2,4-triazole, 1H- and 2H-isoindole, and 1H- and 2H-pyrazole. Tautomeric forms can be in equilibrium or sterically locked into one form by appropriate substitution.

Compounds of the disclosure also include all isotopes of atoms occurring in the intermediates or final compounds. Isotopes include those atoms having the same atomic number but different mass numbers. For example, isotopes of hydrogen include tritium and deuterium. One or more constituent atoms of the compounds of the disclosure can be replaced or substituted with isotopes of the atoms in natural or non-natural abundance. In some embodiments, the compound includes at least one deuterium atom. For example, one or more hydrogen atoms in a compound of the present disclosure can be replaced or substituted by deuterium. In some embodiments, the compound includes two or more deuterium atoms. In some embodiments, the compound includes 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 or 12 deuterium atoms. Synthetic methods for including isotopes into organic compounds are known in the art (Deuterium Labeling in Organic Chemistry by Alan F. Thomas (New York, N.Y., Appleton-Century-Crofts, 1971; The Renaissance of H/D Exchange by Jens Atzrodt, Volker Derdau, Thorsten Fey and Jochen Zimmermann, Angew. Chem. Int. Ed. 2007, 7744-7765; The Organic Chemistry of Isotopic Labelling by James R. Hanson, Royal Society of Chemistry, 2011). Isotopically labeled compounds can used in various studies such as NMR spectroscopy, metabolism experiments, and/or assays.

Substitution with heavier isotopes such as deuterium, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances. (A. Kerekes et. al. J. Med Chem. 2011, 54, 201-210; R. Xu et. al. J. Label Compd Radiopharm. 2015, 58, 308-312).

The term, “compound,” as used herein is meant to include all stereoisomers, geometric iosomers, tautomers, and isotopes of the structures depicted. The term is also meant to refer to compounds of the disclosure, regardless of how they are prepared, e.g., synthetically, through biological process (e.g., metabolism or enzyme conversion), or a combination thereof.

All compounds, and pharmaceutically acceptable salts thereof, can be found together with other substances such as water and solvents (e.g., in the form of hydrates and solvates) or can be isolated. When in the solid state, the compounds described herein and salts thereof may occur in various forms and may, e.g., take the form of solvates, including hydrates. The compounds may be in any solid state form, such as a polymorph or solvate, so unless clearly indicated otherwise, reference in the specification to compounds and salts thereof should be understood as encompassing any solid state form of the compound.

In some embodiments, the compounds of the disclosure, or salts thereof, are substantially isolated. By “substantially isolated” is meant that the compound is at least partially or substantially separated from the environment in which it was formed or detected. Partial separation can include, for example, a composition enriched in the compounds of the disclosure. Substantial separation can include compositions containing at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, at least about 95%, at least about 97%, or at least about 99% by weight of the compounds of the disclosure, or salt thereof. Methods for isolating compounds and their salts are routine in the art.

The phrase “pharmaceutically acceptable” is employed herein to refer to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.

The present disclosure also includes pharmaceutically acceptable salts of the compounds described herein. As used herein, “pharmaceutically acceptable salts” refers to derivatives of the disclosed compounds wherein the parent compound is modified by converting an existing acid or base moiety to its salt form. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable salts of the present disclosure include the non-toxic salts of the parent compound formed, for example, from non-toxic inorganic or organic acids.

Synthesis

As will be appreciated by those skilled in the art, the compounds provided herein, including salts and stereoisomers thereof, can be prepared using known organic synthesis techniques and can be synthesized according to any of numerous possible synthetic routes.

The reactions for preparing compounds of the disclosure can be carried out in suitable solvents which can be readily selected by one of skill in the art of organic synthesis. Suitable solvents can be substantially nonreactive with the starting materials (reactants), the intermediates, or products at the temperatures at which the reactions are carried out, e.g., temperatures which can range from the solvent's freezing temperature to the solvent's boiling temperature. A given reaction can be carried out in one solvent or a mixture of more than one solvent. Depending on the particular reaction step, suitable solvents for a particular reaction step can be selected by the skilled artisan.

Preparation of compounds of the disclosure can involve the protection and deprotection of various chemical groups. The need for protection and deprotection, and the selection of appropriate protecting groups, can be readily determined by one skilled in the art. The chemistry of protecting groups can be found, for example, in T. W. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, 3rd. Ed., Wiley & Sons, Inc., New York (1999), which is incorporated herein by reference in its entirety.

Reactions can be monitored according to any suitable method known in the art. For example, product formation can be monitored by spectroscopic means, such as nuclear magnetic resonance spectroscopy (e.g., ¹H or ¹³C), infrared spectroscopy, spectrophotometry (e.g., UV-visible), or mass spectrometry, or by chromatography such as high performance liquid chromatography (HPLC) or thin layer chromatography.

The expressions, “ambient temperature,” “room temperature,” and “r.t.”, as used herein, are understood in the art, and refer generally to a temperature, e.g. a reaction temperature, that is about the temperature of the room in which the reaction is carried out, for example, a temperature from about 20° C. to about 30° C.

Compounds of formula S-11 can be prepared via the synthetic route as outlined in Scheme 1. The commercially available starting material S-1 can undergo a coupling reaction to adduct S-2, in which M is a boronic acid, a boronic ester or an appropriately substituted metal (e.g., M is B(OR)₂, Sn(Alkyl)₃, Zn-Hal, etc.), under standard Suzuki cross-coupling conditions (e.g., in the presence of a palladium catalyst and a suitable base) (Tetrahedron 2002, 58, 9633-9695), or standard Stille cross-coupling conditions (e.g., in the presence of a palladium catalyst) (ACS Catalysis 2015, 5, 3040-3053), or standard Negishi cross-coupling conditions (e.g., in the presence of a palladium catalyst) (ACS Catalysis 2016, 6, 1540-1552), to give derivative S-3. Reduction of the nitro group of compound S-3 under appropriate conditions can deliver compound S-4. Compound S-4 can undergo a halogenation reaction, such as electrophilic aromatic substitution (SEAT), with an appropriate reagent, such as A-bromosuccinimide (NBS), to afford compound S-5 (Hal is a halide, such as F, Cl, Br, or I). Halide displacement of reagent S-6 with intermediate S-5 via nucleophilic substitution (S_(N)2) generates intermediate S-7. Compound S-7 can undergo an amination reaction, such as a Buchwald-Hartwig coupling (Chem. Sci. 2011, 2, 27-50) in the presence of a palladium catalyst (e.g., tris(dibenzylideneacetone)dipalladium(0)), appropriate ligand (e.g., 2′-(di-tert-butylphosphino)-N,N-dimethylbiphenyl-2-amine), and a base (e.g, sodium tert-butoxide) to afford diamine S-8. Compound S-8 can be coupled with a carboxylic acid adduct of formula S-9, using an appropriate coupling reagent (e.g. HATU, BOP, or PyBOP), to afford compound S-10. Finally, cyclization of compound S-10 at elevated temperature in the presence of a suitable reagent, such as acetic acid, generates compound S-11.

Alternatively, compound S-11 can be prepared via the synthetic route as outlined in Scheme 2. Acylation of compound S-8 with adduct S-12 (Hal is a halide, such as F, Cl, Br, or I) affords intermediate S-10. Cyclization of compound S-10 at elevated temperature in the presence of a suitable reagent, such as acetic acid, generates compound S-l1.

Compounds of formula S-21 can be prepared via the synthetic route as outlined in Scheme 3. Treatment of commercially available compound S-13 with an appropriate reagent, such as phosphoryl chloride (POCl₃), at elevated temperature can afford the chloride adduct S-14. Chloride displacement of compound S-14 via nucleophilic substitution with aqueous ammonia at elevated temperature can deliver amine S-15. Compound S-15 can then be selectively coupled to an adduct of formula S-2, in which M is a boronic acid, a boronic ester or an appropriately substituted metal (e.g., M is B(OR)₂, Sn(Alkyl)₃, Zn-Hal, etc.), under standard Suzuki cross-coupling conditions (e.g., in the presence of a palladium catalyst and a suitable base), or standard Stille cross-coupling conditions (e.g., in the presence of a palladium catalyst), or standard Negishi cross-coupling conditions (e.g., in the presence of a palladium catalyst), to give derivative S-16. Condensation of compound S-16 with a carbonyl adduct S-17 (Hal is a halide, such as F, Cl, Br, or I) at elevated temperature can generate compound S-18. Tricyclic compound S-18 can undergo a halogenation reaction, such as electrophilic aromatic substitution (S_(E)Ar), with an appropriate reagent, such as A-bromosuccinimide (NBS), to afford compound S-19 (Hal is a halide, such as F, Cl, Br, or I). Introduction of R¹ can then be achieved by the coupling of compound S-19 with an adduct S-20, using similar conditions as described for the preparation of compound S-16 from compound S-15, to afford compound S-21.

Alternatively, compounds of formula S-21 can be prepared via the synthetic route as outlined in Scheme 4. Condensation of compound S-15 with a carbonyl adduct of formula S-17 (Hal is a halide, such as Cl, Br, or I) at elevated temperature can generate compound S-22. Compound S-22 can then be selectively coupled to an adduct S-2, in which M is a boronic acid, a boronic ester or an appropriately substituted metal [e.g., M is B(OR)₂, Sn(Alkyl)₃, Zn-Hal, etc.], under standard Suzuki cross-coupling conditions (e.g., in the presence of a palladium catalyst and a suitable base), or standard Stille cross-coupling conditions (e.g., in the presence of a palladium catalyst), or standard Negishi cross-coupling conditions (e.g., in the presence of a palladium catalyst), to give a derivative of formula S-18. Compound S-21 can then be prepared from compound S-18 via the synthetic route as outlined in Scheme 3.

In addition, compound S-21 can be prepared by employing the steps described above in an alternative order. Initial halogenation of compound S-22 using an appropriate reagent, such as A-iodosuccinimide (NIS), can produce a dihalide intermediate which can undergo selective coupling to an adduct S-20 following the synthetic sequence from S-18 to S-21 as shown above in Scheme 3. A similar coupling strategy to an adduct S-2 as shown above in Scheme 4 can be followed to provide access to compound S-21.

Alternatively, compound S-21 can be prepared via the synthetic route as outlined in Scheme 5. Condensation of compound S-15 with a carbonyl adduct S-23 (Hal is a halide, such as Cl, Br, or I) at elevated temperature can generate compound S-24. Compound S-24 can then be selectively coupled to an adduct S-2, in which M is a boronic acid, a boronic ester or an appropriately substituted metal [e.g., M is B(OR)₂, Sn(Alkyl)₃, Zn-Hal, etc.], under standard Suzuki cross-coupling conditions (e.g., in the presence of a palladium catalyst and a suitable base), or standard Stille cross-coupling conditions (e.g., in the presence of a palladium catalyst), or standard Negishi cross-coupling conditions (e.g., in the presence of a palladium catalyst), to give a derivative S-25. Compound S-25 can undergo a halogenation reaction, such as electrophilic aromatic substitution (S_(E)Ar), with an appropriate reagent, such as N-bromosuccinimide (NBS), to afford compound S-26 (Hal is a halide, such as Cl, Br, or I). Introduction of R¹ can then be achieved by the coupling of compound S-26 with an adduct S-20, using similar conditions as described for the preparation of compound S-25 from compound S-24, to afford compound S-27. Compound S-27 can undergo a second halogenation reaction, such as electrophilic aromatic substitution (S_(E)Ar), with an appropriate reagent, such as N-bromosuccinimide (NBS), to afford compound S-28 (Hal is a halide, such as Cl, Br, or I). Introduction of Cy² can then be achieved by the coupling of compound S-28 with an adduct S-29, using similar conditions as described for the preparation of compound S-25 from compound S-24, to afford compound S-21.

Compounds of formula S-33 can be prepared via the synthetic route as outlined in Scheme 6. The commercially available starting material S-30 can undergo a selective coupling reaction with an adduct S-2, in which M is a boronic acid, a boronic ester or an appropriately substituted metal [e.g., M is B(OR)₂, Sn(Alkyl)₃, Zn-Hal, etc.], under standard Suzuki cross-coupling conditions (e.g., in the presence of a palladium catalyst and a suitable base), or standard Stille cross-coupling conditions (e.g., in the presence of a palladium catalyst), or standard Negishi cross-coupling conditions (e.g., in the presence of a palladium catalyst), to give a derivative S-31. Compound S-32 can be prepared by the reaction of compound S-31 with aqueous ammonia, using similar conditions as described for the preparation of compound S-15 from compound S-14 in Scheme 3. Compound S-33 can then be prepared from compound S-32 via the synthetic route as outlined in Scheme 3 starting from compound S-16.

Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, suppositories, sterile injectable solutions, and sterile packaged powders. In some embodiments, the composition is suitable for topical administration.

In preparing a formulation, the active compound can be milled to provide the appropriate particle size prior to combining with the other ingredients. If the active compound is substantially insoluble, it can be milled to a particle size of less than 200 mesh. If the active compound is substantially water soluble, the particle size can be adjusted by milling to provide a substantially uniform distribution in the formulation, e.g. about 40 mesh.

The compounds of the disclosure may be milled using known milling procedures such as wet milling to obtain a particle size appropriate for tablet formation and for other formulation types. Finely divided (nanoparticulate) preparations of the compounds of the disclosure can be prepared by processes known in the art see, e.g., WO 2002/000196.

Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, water, syrup, and methyl cellulose. The formulations can additionally include: lubricating agents such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl- and propylhydroxy-benzoates; sweetening agents; and flavoring agents. The compositions described herein can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art.

In some embodiments, the pharmaceutical composition comprises silicified microcrystalline cellulose (SMCC) and at least one compound described herein, or a pharmaceutically acceptable salt thereof. In some embodiments, the silicified microcrystalline cellulose comprises about 98% microcrystalline cellulose and about 2% silicon dioxide w/w.

In some embodiments, the composition is a sustained release composition comprising at least one compound described herein, or a pharmaceutically acceptable salt thereof, and at least one pharmaceutically acceptable carrier or excipient. In some embodiments, the composition comprises at least one compound described herein, or a pharmaceutically acceptable salt thereof, and at least one component selected from microcrystalline cellulose, lactose monohydrate, hydroxypropyl methylcellulose and polyethylene oxide. In some embodiments, the composition comprises at least one compound described herein, or a pharmaceutically acceptable salt thereof, and microcrystalline cellulose, lactose monohydrate and hydroxypropyl methylcellulose. In some embodiments, the composition comprises at least one compound described herein, or a pharmaceutically acceptable salt thereof, and microcrystalline cellulose, lactose monohydrate and polyethylene oxide. In some embodiments, the composition further comprises magnesium stearate or silicon dioxide. In some embodiments, the microcrystalline cellulose is Avicel PH102™. In some embodiments, the lactose monohydrate is Fast-flo 316™. In some embodiments, the hydroxypropyl methylcellulose is hydroxypropyl methylcellulose 2208 K4M (e.g., Methocel K4 M Premier™) and/or hydroxypropyl methylcellulose 2208 K100LV (e.g., Methocel K00LV™). In some embodiments, the polyethylene oxide is polyethylene oxide WSR 1105 (e.g, Polyox WSR 1105™).

In some embodiments, a wet granulation process is used to produce the composition. In some embodiments, a dry granulation process is used to produce the composition.

The compositions can be formulated in a unit dosage form, each dosage containing from, for example, about 5 mg to about 1000 mg, about 5 mg to about 100 mg, about 100 mg to about 500 mg or about 10 to about 30 mg, of the active ingredient. In some embodiments, each dosage contains about 10 mg of the active ingredient. In some embodiments, each dosage contains about 50 mg of the active ingredient. In some embodiments, each dosage contains about 25 mg of the active ingredient. The term “unit dosage forms” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient.

The components used to formulate the pharmaceutical compositions are of high purity and are substantially free of potentially harmful contaminants (e.g, at least National Food grade, generally at least analytical grade, and more typically at least pharmaceutical grade). Particularly for human consumption, the composition is preferably manufactured or formulated under Good Manufacturing Practice standards as defined in the applicable regulations of the U.S. Food and Drug Administration. For example, suitable formulations may be sterile and/or substantially isotonic and/or in full compliance with all Good Manufacturing Practice regulations of the U.S. Food and Drug Administration.

The active compound can be effective over a wide dosage range and is generally administered in a pharmaceutically effective amount. It will be understood, however, that the amount of the compound actually administered will usually be determined by a physician, according to the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like.

The therapeutic dosage of a compound of the present disclosure can vary according to, e.g., the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound of the disclosure in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g, hydrophobicity), and the route of administration. For example, the compounds of the disclosure can be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w/v of the compound for parenteral administration. Some typical dose ranges are from about 1 pg/kg to about 1 g/kg of body weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems.

For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid pre-formulation composition containing a homogeneous mixture of one or more compounds described herein. When referring to these pre-formulation compositions as homogeneous, the active ingredient is typically dispersed evenly throughout the composition so that the composition can be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. This solid pre-formulation is then subdivided into unit dosage forms of the type described above containing from, for example, 0.1 to about 500 mg of the active ingredient of the present disclosure.

The tablets or pills of the present disclosure can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate.

The liquid forms in which the compounds, or compositions as described herein can be incorporated for administration orally or by injection include aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.

Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. In some embodiments, the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions in can be nebulized by use of inert gases. Nebulized solutions may be breathed directly from the nebulizing device or the nebulizing device can be attached to a face masks tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions can be administered orally or nasally from devices which deliver the formulation in an appropriate manner.

Topical formulations can contain one or more conventional carriers. In some embodiments, ointments can contain water and one or more hydrophobic carriers selected from, e.g., liquid paraffin, polyoxyethylene alkyl ether, propylene glycol, white Vaseline, and the like. Carrier compositions of creams can be based on water in combination with glycerol and one or more other components, e.g., glycerinemonostearate, PEG-glycerinemonostearate and cetylstearyl alcohol. Gels can be formulated using isopropyl alcohol and water, suitably in combination with other components such as, e.g., glycerol, hydroxyethyl cellulose, and the like. In some embodiments, topical formulations contain at least about 0.1, at least about 0.25, at least about 0.5, at least about 1, at least about 2 or at least about 5 wt % of the compound of the disclosure. The topical formulations can be suitably packaged in tubes of, e.g., 100 g which are optionally associated with instructions for the treatment of the select indication, e.g., psoriasis or other skin condition.

The amount of compound or composition administered to a patient will vary depending upon what is being administered, the purpose of the administration, such as prophylaxis or therapy, the state of the patient, the manner of administration, and the like. In therapeutic applications, compositions can be administered to a patient already suffering from a disease in an amount sufficient to cure or at least partially arrest the symptoms of the disease and its complications. Effective doses will depend on the disease condition being treated as well as by the judgment of the attending clinician depending upon factors such as the severity of the disease, the age, weight and general condition of the patient, and the like.

The compositions administered to a patient can be in the form of pharmaceutical compositions described above. These compositions can be sterilized by conventional sterilization techniques, or may be sterile filtered. Aqueous solutions can be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile aqueous carrier prior to administration. The pH of the compound preparations typically will be between 3 and 11, more preferably from 5 to 9 and most preferably from 7 to 8. It will be understood that use of certain of the foregoing excipients, carriers, or stabilizers will result in the formation of pharmaceutical salts.

The therapeutic dosage of a compound of the present disclosure can vary according to, for example, the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of the compounds in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, compounds of the present disclosure can be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w/v of the compound for parenteral administration. Some typical dose ranges are from about 1 μg/kg to about 1 g/kg of body weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems.

Compounds described herein can also be formulated in combination with one or more additional active ingredients, which can include any pharmaceutical agent such as anti-viral agents, vaccines, antibodies, immune enhancers, immune suppressants, anti-inflammatory agents and the like.

Labeled Compounds and Assay Methods

Another aspect of the present disclosure relates to labeled compounds of the disclosure (radio-labeled, fluorescent-labeled, etc.) that would be useful not only in imaging techniques but also in assays, both in vitro and in vivo, for localizing and quantitating FGFR3 protein in tissue samples, including human, and for identifying FGFR3 ligands by inhibition binding of a labeled compound. Substitution of one or more of the atoms of the compounds of the present disclosure can also be useful in generating differentiated ADME (Adsorption, Distribution, Metabolism and Excretion). Accordingly, the present disclosure includes FGFR binding assays that contain such labeled or substituted compounds.

The present disclosure further includes isotopically-labeled compounds of the disclosure. An “isotopically” or “radio-labeled” compound is a compound of the disclosure where one or more atoms are replaced or substituted by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature (i.e., naturally occurring). Suitable radionuclides that may be incorporated in compounds of the present disclosure include but are not limited to ²H (also written as D for deuterium), ³H (also written as T for tritium), ¹¹C, ¹³C, ¹⁴C, ¹³N, ¹⁵N, ¹⁵O, ¹⁷O, ¹⁸O, ¹⁸F, ³⁵S, ³⁶Cl, ⁸²Br, ⁷⁵Br, ⁷⁶Br, ⁷⁷Br, ¹²³I, ¹²⁴I, ¹²⁵I and ¹³¹I. For example, one or more hydrogen atoms in a compound of the present disclosure can be replaced by deuterium atoms (e.g., one or more hydrogen atoms of a C₁₋₆ alkyl group of Formula (I) can be optionally substituted with deuterium atoms, such as-CD₃ being substituted for —CH₃). In some embodiments, alkyl groups in Formula (I) can be perdeuterated.

One or more constituent atoms of the compounds presented herein can be replaced or substituted with isotopes of the atoms in natural or non-natural abundance. In some embodiments, the compound includes at least one deuterium atom. In some embodiments, the compound includes two or more deuterium atoms. In some embodiments, the compound includes 1-2, 1-3, 1-4, 1-5, or 1-6 deuterium atoms. In some embodiments, all of the hydrogen atoms in a compound can be replaced or substituted by deuterium atoms.

Synthetic methods for including isotopes into organic compounds are known in the art (Deuterium Labeling in Organic Chemistry by Alan F. Thomas (New York, N.Y., Appleton-Century-Crofts, 1971; The Renaissance of H/D Exchange by Jens Atzrodt, Volker Derdau, Thorsten Fey and Jochen Zimmermann, Angew. Chem. Int. Ed. 2007, 7744-7765; The Organic Chemistry of Isotopic Labelling by James R. Hanson, Royal Society of Chemistry, 2011). Isotopically labeled compounds can be used in various studies such as NMR spectroscopy, metabolism experiments, and/or assays.

Substitution with heavier isotopes, such as deuterium, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances, (see e.g., A. Kerekes et. al. J. Med Chem. 2011, 54, 201-210; R. Xu et. al. J. Label Compd Radiopharm. 2015, 58, 308-312). In particular, substitution at one or more metabolism sites may afford one or more of the therapeutic advantages.

The radionuclide that is incorporated in the instant radio-labeled compounds will depend on the specific application of that radio-labeled compound. For example, for in vitro adenosine receptor labeling and competition assays, compounds that incorporate ³H, ¹⁴C, ⁸²Br, ¹²⁵I, ¹³¹I or ³⁵S can be useful. For radio-imaging applications ¹¹C, ¹⁸F, ¹²⁵I, ¹²³I, ¹²⁴I, ¹³¹I, ⁷⁵Br, ⁷⁶Br or ⁷⁷Br can be useful.

It is understood that a “radio-labeled” or “labeled compound” is a compound that has incorporated at least one radionuclide. In some embodiments, the radionuclide is selected from the group consisting of ³H, ¹⁴C, ¹²⁵I, ³⁵S and ⁸²Br.

The present disclosure can further include synthetic methods for incorporating radio-isotopes into compounds of the disclosure. Synthetic methods for incorporating radio-isotopes into organic compounds are well known in the art, and an ordinary skill in the art will readily recognize the methods applicable for the compounds of disclosure.

A labeled compound of the disclosure can be used in a screening assay to identify and/or evaluate compounds. For example, a newly synthesized or identified compound (i.e., test compound) which is labeled can be evaluated for its ability to bind an FGFR3 protein by monitoring its concentration variation when contacting with the FGFR3, through tracking of the labeling. For example, a test compound (labeled) can be evaluated for its ability to reduce binding of another compound which is known to bind to a FGFR3 protein (i.e., standard compound). Accordingly, the ability of a test compound to compete with the standard compound for binding to the FGFR3 protein directly correlates to its binding affinity. Conversely, in some other screening assays, the standard compound is labeled and test compounds are unlabeled. Accordingly, the concentration of the labeled standard compound is monitored in order to evaluate the competition between the standard compound and the test compound, and the relative binding affinity of the test compound is thus ascertained.

Kits

The present disclosure also includes pharmaceutical kits useful, for example, in the treatment or prevention of FGFR-associated diseases or disorders, such as cancer and other diseases referred to herein which include one or more containers containing a pharmaceutical composition comprising a therapeutically effective amount of a compound of the disclosure. Such kits can further include, if desired, one or more of various conventional pharmaceutical kit components, such as, for example, containers with one or more pharmaceutically acceptable carriers, additional containers, etc., as will be readily apparent to those skilled in the art. Instructions, either as inserts or as labels, indicating quantities of the components to be administered, guidelines for administration, and/or guidelines for mixing the components, can also be included in the kit.

The disclosure will be described in greater detail by way of specific examples. The following examples are offered for illustrative purposes, and are not intended to limit the disclosure in any manner. Those of skill in the art will readily recognize a variety of non-critical parameters which can be changed or modified to yield essentially the same results. The compounds of the Examples were found to be inhibitors of FGFR3 as described below.

Example A: FGFR Enzymatic Assay

The inhibitor potency of the exemplified compounds was determined in an enzyme discontinuous assay that measures peptide phosphorylation using FRET measurements to detect product formation. Inhibitors were serially diluted in DMSO and a volume of 0.2 μL was transferred to the wells of a 384-well plate. A 5 μL/well volume of enzyme isoforms of FGFR (-1, -2, -3 wild-type and mutant isoforms, -4) including phosphorylated and un-phosphorylated proteins diluted in assay buffer (50 mM HEPES, 10 mM MgCl₂, 1 mM EGTA, 0.01% Tween-20, 5 mM DTT, pH 7.5) was added to the plate and pre-incubated with inhibitor for 5 to 15 minutes at ambient temperature. Appropriate controls (enzyme blank and enzyme with no inhibitor) were included on the plate. The reaction was initiated by the addition of a 5 μL/well volume containing both biotinylated EQEDEPEGDYFEWLE peptide substrate (SEQ ID NO: 1) and ATP in assay buffer. The 10 μL/well reaction concentration of the peptide substrate was 500 nM whereas the ATP concentration was maintained near or below the ATP Km. The ATP Km values were pre-determined in a separate series of experiments. The reaction plate was incubated at 25° C. for 1 hr and the reactions were ended with the addition of 5 μL/well of quench solution (50 mM Tris, 150 mM NaCl, 0.5 mg/mL BSA, pH 7.8; 45 mM EDTA, 600 nM staurosporin, with Perkin Elmer Lance Reagents at 3.75 nM Eu-antibody PY20 and 180 nM APC-Streptavidin). The plate was allowed to equilibrate for ˜10 minutes at ambient temperature before scanning on a PheraStar plate reader (BMG Labtech) instrument.

Either GraphPad prism or XLfit was used to analyze the data. The IC₅₀ values were derived by fitting the data to a four parameter logistic equation producing a sigmoidal dose-response curve with a variable Hill coefficient. Prism equation: Y=Bottom+(Top−Bottom)/(1+10{circumflex over ( )}((LogIC₅₀−X)*Hill slope)); XLfit equation: Y=(A+((B−A)/(1+((X/C){circumflex over ( )}D)))) where X is the logarithm of inhibitor concentration and Y is the response. Compounds having an IC₅₀ of 1 μM or less are considered active.

Table 1 provides IC₅₀ data for compounds of the disclosure assayed in the FGFR Enzymatic Assay after dilution in assay buffer, added to the plate and pre-incubated for 4 hours. The symbol: “+” indicates an IC₅₀ less than 10 nM; “++” indicates an IC₅₀ greater than or equal to 10 nM but less than 100 nM; “+++” indicates an IC₅₀ greater than or equal to 100 nM but less than 400 nM; and “++++” indicates an IC₅₀ greater than or equal to 400 nM.

The data in Table 1 was measured in wild-type un-phosphorylated FGFR3 protein.
